How this conversion works
Everything happens locally in your browser, using the HTML5 Canvas API — the image is read, drawn onto a canvas and re-exported in the new format without ever being sent to a server. That means instant conversion and full privacy.
About JPG and WEBP
WEBP usually produces much smaller files than JPG or PNG at equivalent visual quality, and it supports transparency.
Frequently asked questions
Is my image uploaded to a server?
No. Conversion happens entirely in your browser using the Canvas API — the image never leaves your computer.
Is there a size limit?
Yes, the limit is 20MB per image, to avoid browser slowdowns with very large files.
